Topped with a chunky peanut butter frosting, this portable “Coke cake” is a fun and easy summer party dessert.

Summer is the season for ultra-portable sheet cakes, and it’s hard to imagine a more kid-friendly cake than this Coca-Cola-infused sheet cake topped with a broiled peanut butter frosting.

Using just one pan, it requires no assembly or stacking, and the frosting spreads right on top. If you use a glass baking dish with a snap-on lid, you’ll be out the door and headed to your picnic, party, or cookout in a flash — leaving more time for fun in the sun.

This cake is full of surprises, starting with the soda.

The frosting is made up of butter, milk, and these beautiful things — peanut butter, salted peanuts, and brown sugar.

Fresh from the oven, the warm cake is gently frosted and then returned to the oven for a quick (just seconds, really) broil to melt and set the frosting.

You’ll love this cake. The soda lends a subtle tang to the light chocolate cake, but the real winner here is the frosting. It’s sweet, salty, decadent, and paired with the cake, everything you could ask for in a summer party snack cake.
